Holy shit... that could still be used. Was there an actual name for this class?

The old Treknology publicaitons had her listed as the Ariel-class "shuttlecarrier". The study model appeared in a few "graveyard" scenes in TNG, and may be known as the "Gage type"...

Actually, there were two different (but similar-looking) McQuarrie study models. One was used in the Qualor II surplus depot in "Unification," and the other was used as a docked background ship in Spacedock in Star Trek III. It would be incorrect to refer to it as the "Gage-type," because the Gage was only mentioned in a first draft of DS9's "Emissary" and was neither seen nor spoken of in the final televised draft.

I will accept your stipulation. The only sources I could come up with had the study models as the "Gage type", but that may be in error (as you suggest).
